Cura slicer settings for the Creality Ender 3, V2, and V3 SE

Which printers this covers

This guide applies to the Creality Ender 3, Ender 3 V2, and Ender 3 V3 SE — three machines that share a common lineage but differ in ways that affect your slicer settings. The original Ender 3 and V2 use a Bowden extruder: the motor sits on the frame and pushes filament through a PTFE tube to the hotend. The V3 SE ships with a direct-drive Sprite extruder, where the motor rides on the carriage directly above the nozzle. That single difference changes retraction settings significantly, so pay attention to the variant-specific sections below.

All settings assume Cura 5.x, a stock 0.4 mm nozzle, and PLA as the primary material unless stated otherwise.

Setting up your printer profile

If Cura does not already have your printer configured, go to Preferences → Printers → Add a printer and search for your model:

1. Ender 3 — select Creality Ender 3 2. Ender 3 V2 — select Creality Ender 3 V2 3. Ender 3 V3 SE — select Creality Ender 3 V3 SE (available in Cura 5.6 and later)

Cura pre-fills the build volume, bed shape, and start/end G-code for each variant. Do not change the nozzle offset or build volume unless you have physically measured them — incorrect values cause skirts and brims to print outside the reachable area.

Layer height

Layer height is the single biggest lever on print time versus surface detail:

1. 0.12 mm — fine detail, slow. Use for display pieces, figurines, or small parts where surface finish matters most. 2. 0.20 mm — the standard starting point. Reliable on all three machines without further tuning. 3. 0.28 mm — fast, visibly layered. Fine for prototypes, brackets, or anything that will be sanded or painted.

Stick to multiples of 0.04 mm on all Ender 3 variants. The Z lead screw hits full motor steps at these values, which reduces Z banding artefacts.

Print temperatures

These are starting points. Your particular roll of filament may need ±5–10 °C adjustment — run a temperature tower when switching brands.

PLA:

• Nozzle: 200–210 °C
• Bed: 55–60 °C

PETG:

• Nozzle: 230–240 °C
• Bed: 70–80 °C
• If you are seeing stringing, reduce nozzle temperature by 5 °C before touching retraction.

ABS / ASA:

• Nozzle: 240–250 °C
• Bed: 90–100 °C
• The Ender 3 has no enclosure from the factory. Without one, ABS warps badly on anything larger than a small coin. An enclosure is effectively required for reliable ABS on these machines — do not expect consistent results without one.

Print speed

This is where the Bowden and direct-drive variants differ most.

Ender 3 and V2 (Bowden):

• Print speed: 40–50 mm/s
• Infill speed: 60–70 mm/s
• Outer wall speed: 25–35 mm/s
• Travel speed: 120–150 mm/s

Pushing the Bowden Ender 3 past 60 mm/s on perimeters typically causes under-extrusion and ringing artefacts. The long PTFE tube introduces pressure lag that the stock firmware cannot fully compensate without Linear Advance (M900) tuned and enabled — which requires a compatible mainboard.

Ender 3 V3 SE (direct drive):

• Print speed: 60–80 mm/s
• Outer wall speed: 40–50 mm/s
• Travel speed: 150–200 mm/s

The V3 SE ships with input shaping pre-calibrated at the factory, which helps suppress ringing at higher speeds. That said, the bed springs and eccentric nuts degrade with use. If ringing returns at speeds that previously worked cleanly, check your gantry wheel tension before adjusting slicer settings.

Retraction — the most important variant difference

Retraction pulls filament back during travel moves to reduce stringing. The correct value depends almost entirely on whether you have a Bowden or direct-drive extruder.

Ender 3 and V2 (Bowden):

• Retraction distance: 5–6 mm
• Retraction speed: 45–50 mm/s

Do not exceed 7 mm retraction, particularly with PETG — it pulls molten filament too far back and causes grinding inside the tube.

Ender 3 V3 SE (direct drive):

• Retraction distance: 1–2 mm
• Retraction speed: 35–45 mm/s

If you have fitted a direct-drive conversion kit to an original Ender 3 or V2, use these values, not the Bowden settings above. Using 5–6 mm retraction on a direct-drive machine grinds through the filament and causes clogs within a few prints.

Enable combing mode (set to Not in skin) in Cura to reduce the number of retractions across infill areas. This shortens print time and reduces wear on the extruder gear.

Infill

For most functional prints, 20–25% gyroid or grid infill is sufficient. For decorative parts, 10–15% works fine. Structural parts — brackets, clips, and load-bearing mounts — benefit from 40% or above.

Gyroid infill is equally strong in all directions, which makes it a solid general-purpose choice. Lightning infill is only worth using for large display pieces where you want a solid surface but filament cost and weight matter more than strength.

Cooling

PLA: Run the part-cooling fan at 100% from layer 3 onward. PLA needs active cooling to bridge and overhang cleanly.

PETG: Reduce the fan to 30–50%. PETG bonds better between layers with less cooling, but too much residual heat allows the nozzle to drag strings across the part.

ABS / ASA: Fan off, or no more than 15%. Aggressive cooling causes layer delamination and warping.

Bed adhesion

1. Always level the bed at operating temperature, not cold. Thermal expansion changes the gap between nozzle and bed. 2. Set first layer height to 0.2 mm regardless of your normal layer height. 3. Set first layer speed to 20–25 mm/s. 4. If prints are not sticking: clean the build surface with isopropyl alcohol, re-check Z offset, and confirm the bed temperature has stabilised before the print begins.

A brim of 5–8 mm is worth enabling for any part with a small footprint or sharp corners. A raft is rarely necessary for PLA but helps significantly with ABS.

Common problems and their fixes

Stringing — reduce nozzle temperature by 5 °C first. If that does not resolve it, increase retraction distance by 0.5 mm (within the limits above for your extruder type) and enable combing.

Layer shifting — print speed is likely too high for the current belt and wheel tension. Tighten belts until they have a slight spring when plucked, then reduce print speed by 10 mm/s and test again.

Under-extrusion — raise nozzle temperature by 5 °C, check the Bowden tube clip and coupler for gaps at the hotend end, and inspect the extruder idler arm for cracks. The plastic idler arm on the original Ender 3 is a well-known failure point.

First layer not sticking — re-level the bed at operating temperature and clean the build surface. If you have a glass bed, allow it to fully reach temperature before starting the print; a cold start on glass almost always fails.

Ringing on outer walls — reduce outer wall speed, check eccentric nut tension on the X carriage wheels, and confirm the X gantry bar is secure at both upright ends.

When to mail it in

If under-extrusion, grinding, or layer defects persist after working through the settings above, the problem is usually hardware rather than software — a worn PTFE liner, a cracked extruder idler arm, a partial hot end clog, or a failing thermistor. These are all repairable faults but require disassembly and in some cases specialist tools to do safely. If you would rather not risk making things worse, Hark Tech offers a mail-in 3D printer repair service for Ender 3 variants and other FDM machines. Get in touch via the contact page with a description of the fault and a short video if you can — most issues can be assessed and quoted within a few working days.
